The distribution exempts from licensed radio frequency frequency range Permission Levels and can notify wireless telecom equipment 102, such as establishes the phase in radio bearer Between, during wireless heterogeneous networks (RRC) configuration process, in RRC connection reconfiguration set in message, and/or can wirelessly communicate In the other control signalings occurred between equipment 102 and the network element of cellular radio.It can be given in cellular radio Radio bearer distribution is exempted from some example embodiments of licensed radio frequency frequency range Permission Levels, and the distribution can be small via main service Area notifies wireless telecom equipment 102.
In some embodiments, for example, based on by RRC/RLC layers and/or NAS layers from one or more such as honeycombs without The configuration that the network element of the eNB and/or mobile management entity (MME) of gauze network are communicated to wireless telecom equipment 102, one or Multiple radio bearers with exempt from being associated between licensed radio frequency frequency range Permission Levels can be via RRC/RLC layers and/or Non-Access Stratum Face (NAS) layer provides.In some embodiments, wireless telecom equipment 102 can determine one or more based on one group of application demand A radio bearer with exempt from being associated between licensed radio frequency frequency range Permission Levels, the application demand can be with the one of cellular radio The configuration that a or multiple network elements provide coexists and/or modifies the configuration.In some embodiments, wireless telecom equipment 102 can provide the instruction of its ability to one or more network elements of cellular radio, for example, whether wireless telecom equipment props up It holds and uses LTE-U component carrier.In some embodiments, one or more network elements of cellular radio can be used related The information of 102 ability of wireless telecom equipment is exempted to permit to determine one group that is associated with the radio bearer for wireless telecom equipment 102 Radio frequency band Permission Levels.In some embodiments, one or more network elements provide one group for wireless telecom equipment 102 and exempt from Licensed radio frequency frequency range Permission Levels and/or exempt from licensed radio frequency frequency range Permission Levels with one group be used for wireless telecom equipment 102 nothing One group of association between line carrying, for example, via RRC/RLC layers and/or NAS layers.In some embodiments, cellular radio Network element can by its inquire wireless telecom equipment 102 ability message and/or wireless telecom equipment 102 can pass through it To the message of the ability of one or more network elements instruction wireless telecom equipment 102, it can be added and/or modify and be used to refer to Show and support LTE-U communication characteristic, such as supports one or more LTE-U component carrier, one or more LTE-U is supported to exempt to permit Radio frequency band supports one or more LTE-U component carrier frequencies, and/or their combination.In some embodiments, honeycomb One or more network elements of wireless network can inquire the ability that carrier wave polymerization is supported in relation to wireless telecom equipment 102, such as Whether wireless telecom equipment 102 is supported using the LTE component carrier in licensed radio frequency frequency range and is exempted from licensed radio frequency frequency range One or more combinations of LTE-U component carrier are communicated.In some embodiments, wireless telecom equipment 102 can be drawn It is divided into and belongs to wireless telecom equipment type, such as existing and/or new UE type, the division can indicates wireless telecom equipment Whether 102 support the combined load for exempting from licensed radio frequency frequency range component carrier using LTE licensed radio frequency frequency range component carrier and LTE-U Wave polymerization.For example, in some embodiments, according to one or more wireless communication protocols in order to support LTE-U component carrier And the one or more classification defined, wireless telecom equipment 102 can be divided into belong to classification 9-U, 10-U, 11-U, 12-U or Other #-U types.
As shown in fig. 6, wireless telecom equipment 102 can execute priorization and multichannel in the uplink service of radio bearer It is multiplexed function 610.In some embodiments, it is prioritized and multiplex function 610 can be held by multiplexing module 318 Row.In some embodiments, it is prioritized and multiplex function 610 can be used as a part of of MAC layer 506 and occur.It is prioritized Can be at least partially based on multiplex function 610 distribute to radio bearer exempt from licensed radio frequency frequency range Permission Levels to hold Row.In some example embodiments, priorization and multiplex function 610 can additionally consider associated any with radio bearer PBR.In this respect, priorization and multiplex function 610 can be performed respective most at least to meet each radio bearer Small packet bit rate.
The MAC PDU size (for example, to given TTI) permitted for component carrier can be to can pass through component carrier road By maximum amount of data effect of contraction.And MAC PDU size can also be in executing priorization and multiplex function 610 It is considered.In this respect, it is given arbitrarily by the possibility that licensed radio frequency frequency range Permission Levels are forced of exempting from of movable radio bearer In the case where constraint, some example embodiments are by data prioritization and multiplexing to realize available MAC in given TTI PDU.Shown in figures 7 and 8 according to the more detailed example of priorization and the multiplexing of the MAC PDU size of allowance and with Under be described about Fig. 7 and 8.
The PBR for exempting from the radio bearer that licensed radio frequency frequency range is forbidden of such as wireless carrier 602 can give highest preferential Grade, and PBR can be forced to obey such as CC1612 and CC2Total available transmission of 614 one group of licensed radio frequency frequency range component carrier provides Source.In some embodiments, MAC control element (CE) and/or other control signalings, which can also be assigned, (and/or is interpreted as having Have) exempt from licensed radio frequency frequency range and forbids Permission Levels, and therefore one group of MAC CD and/or other control signalings can be always by one Or multiple licensed radio frequency frequency range component carriers route and never exempt from the routing of licensed radio frequency frequency range component carrier by any.
The PBR of the preferential radio bearer of the licensed radio frequency frequency range of such as radio bearer 604 can be forced to obey first (for example, arbitrarily exempting to permit to penetrate meeting on any available transfer resource of one group of available licensed radio frequency frequency range component carrier After the PBR for the radio bearer that frequent section is forbidden).Any remainder of the PBR of the preferential radio bearer of licensed radio frequency frequency range Can then it be met by exempting from licensed radio frequency frequency range component carrier.
As described herein above, the data for the carrying for exempting from the permission of licensed radio frequency frequency range of such as radio bearer 606 can be with It is routed by any radio bearer, is in license RF wave band or to exempt to permit RF wave band but regardless of the radio bearer.For example, In some embodiments, the data of the carrying allowed for licensed radio frequency frequency range can pass through available licensed radio frequency frequency range component Carrier resource routing, and the data of the carrying for exempting from the permission of licensed radio frequency frequency range can be by exempting from licensed radio frequency frequency range component Carrier resource routing, unless licensed radio frequency frequency range component carrier resource be licensed radio frequency frequency range allow carrying fill data (or Person at least PBR, if any) there is also available licensed radio frequency frequency range component carrier resources later.In some embodiments, Before using any licensed radio frequency frequency range component carrier resource, the data of the carrying for the permission of licensed radio frequency frequency range can be first It first passes through and exempts from licensed radio frequency frequency range component carrier resource routing.
Fig. 7 shows in accordance with some embodiments in example TTI, will be used for the first radio bearer 702 and second wireless The data prioritization of carrying 704 and the conceptual example being multiplexed on LTE component carrier 714 and LTE-U component carrier 716 Figure 70 0.First radio bearer 702 can be associated with LTE-U and forbid Permission Levels and the second radio bearer 704 that can be associated with LTE-U allows Permission Levels.The RLC PDU that is used for first radio bearer 702 available to MAC layer, can wrap in example TTI 700 bit datas are included, and the PBR of the first radio bearer 702 can be 400 bits.It is available to MAC layer to be used for second wirelessly The RLC PDU of carrying 704, may include 1000 bit datas in example TTI, and the PBR of the second radio bearer 704 can be with It is 100 bits.
It is at least partially based on and exempts from licensed radio frequency frequency range Permission Levels and PBR for the respective of radio bearer, can be use It is executed in the available RLC PDU data of the first radio bearer 702 and the second radio bearer 704 and is prioritized 710 (such as by more Road Multiplexing module 318).In this respect, since the first radio bearer 702 is " LTE-U forbids " radio bearer, the first radio bearer 702 400 bit datas can have highest priority to meet the PBR of the first radio bearer 702.The 100 of second radio bearer 704 Bit data can be given the second highest priority to meet the PBR of the second radio bearer 704.First radio bearer 702 It can be given third highest priority with 300 bit of residue of RLC PDU data, followed by the second radio bearer 704 Available RLC PDU data 900 bit of residue.
In the example in figure 7, the MAC PDU allowance of 800 bits is provided to LTE component carrier 714 and LTE-U component carries Each of wave 716 amounts to and permits 1600 bits.It is at least partially based on and is prioritized 710 result and in individual MAC PDU In the constraint that size is permitted with the first radio bearer 702 and the second radio bearer 704 is associated exempts from licensed radio frequency frequency range permission Grade can execute multiplexing 712 (such as by multiplexing module 318).Thus, for example the PBR of two radio bearers It can be included in the MAC PDU of LTE component carrier 714, occupy 500 bits in 800 bits of its MAC PDU.Due to Available RLC PDU number of 300 bit of residue of the available RLC PDU data of first radio bearer 702 than the second radio bearer 704 According to 900 bit of residue there is higher priority, and cannot be routed by LTE-U component carrier 716, the first radio bearer 300 bit of residue of 702 available RLC PDU data may also be included in that in the MAC PDU of LTE component carrier 714.Second 800 bits in 900 bit of residue of the available RLC PDU data of radio bearer 704 can then be then used to filling LTE-U The not used capacity of 800 bit MAC PDU of component carrier 716.
Fig. 8 is shown in example TTI, and the data prioritization for being used for multiple radio bearers is divided with LTE is multiplexed to Another conceptual exemplary Figure 80 0 on loading gage wave 814 and LTE-U component carrier 816.In the example of fig. 8, first is wireless Carrying 802 can be associated with LTE-U and forbid Permission Levels.The RLC PDU that is used for first radio bearer 802 available to MAC layer, It may include 700 bit datas in example TTI, and the PBR of the first radio bearer 802 can be 400 bits.Second wirelessly holds LTE permission Permission Levels can be associated with by carrying 804.The RLCPDU that is used for second radio bearer 804 available to MAC layer, in example It may include 800 bit datas in TTI, and the PBR of the second radio bearer 804 can be 200 bits.Third radio bearer 806, which can be associated with LTE-U, allows Permission Levels.RLC PDU for third radio bearer 806 available to MAC layer, in example It may include 1000 bit datas in TTI, and the PBR of third radio bearer 806 can be 100 bits.
It is at least partially based on and exempts from licensed radio frequency frequency range Permission Levels and PBR for the respective of radio bearer, can be use It is executed in the available RLC PDU data of the first radio bearer 802, the second radio bearer 804 and third radio bearer 806 preferential Change 810 (such as passing through multiplexing module 318).In this respect, since the first radio bearer 802 is that " LTE-U forbids " is wireless Carrying, 400 bit datas of the first radio bearer 802 can have highest priority to meet the PBR of the first radio bearer 802.It is logical Often, the data of the second radio bearer 804 are higher than the data priority of third radio bearer 806, because the second radio bearer 804 is " LET is preferential " radio bearer and third radio bearer 806 is " LTE permission " radio bearer.It therefore meets the second radio bearer 200 bits of 804 PBR can be given the second highest priority, and meet 100 bits of the PBR of third radio bearer 806 Third highest priority can be given.300 bit of residue of the available PDU data of first radio bearer 802 can be given the 4th Highest priority, next is 600 bit of residue of the available PDU data of the second radio bearer 804, and is finally third 900 bit of residue of the available RLC PDU data of radio bearer 806.
In the example of fig. 8, the MAC PDU allowance of 800 bits is provided to LTE component carrier 814 and LTE-U component carries Each of wave 816 amounts to and permits 1600 bits.It is at least partially based on and is prioritized 810 result and in MAC PDU size standard Perhaps in constraint with radio bearer 802, radio bearer 804 and radio bearer 806 are associated exempts from licensed radio frequency frequency range permission etc. Grade, can execute multiplexing 812 (such as by multiplexing module 318).Thus, for example meeting the first radio bearer 802 400 bits of PBR can be included in the MAC PDU of LTE component carrier 814 because those data will not pass through LTE-U Component carrier transmission.Since the second radio bearer 804 is associated with LTE limit priority grade, meet the second radio bearer 804 200 bits of PBR also may include in the MAC PDU of LTE component carrier 814.Due to 100 ratios of third radio bearer 806 Special PBR can freely be met on LTE-U component carrier 816, and the data of the first radio bearer 802 are prohibited to pass through The transmission of LTE-U component carrier, the space of 200 bit of residue of the MAC PDU of LTE component carrier 814 can wirelessly be held by first Carry 802 additional 200 bit data filling (such as leading to amount to 600 bits from the first radio bearer 802).
100 bit datas of third radio bearer 806 needed for meeting the PBR of third radio bearer 806, may include In the MAC PDU of LTE-U component carrier 816.Due to after all PBR are satisfied, the RLC PDU of the second radio bearer 804 600 bit of residue of data has higher priority than 900 bit of residue of the RLC PDU data of third radio bearer 806, 600 bit of residue of the RLC PDU data of second radio bearer 804 also may include the MAC in LTE-U component carrier 816 It is additional 100 bit (such as amounting to 200 bits) slot milling of the RLC PDU data of third radio bearer 806 in PDU.
It will be appreciated that the technology that the example about Fig. 7 and 8 shows and describes can do necessary modification and be applied to any Number has the various associated radio bearers for exempting from licensed radio frequency frequency range Permission Levels and/or is applied to any number of point Loading gage wave, component carrier include the different number of licensed radio frequency frequency range component that can multiplex uplink data on it Carrier wave and/or exempt from licensed radio frequency frequency range component carrier.It will also be understood that when using the RAT with carrier aggregation capacity rather than LTE When, it can also be using the example technology that show and describe about Fig. 7 and 8.
Fig. 9, which is shown, carries out uplink according to using exempting from licensed radio frequency frequency range component carrier according to some example embodiments The flow chart of the exemplary method of road transmission.In this respect, Fig. 9 is shown according to some example embodiments, can be by such as channel radio Believe the operation that the wireless telecom equipment of equipment 102 executes.One or more processing circuits 310, processor 312, memory 314, Wireless communication interface 316 or multiplexing module 318 can for example provide the one or more for executing and shown in Fig. 9 and describing The mode of operation.
Operation 900 may include: that wireless telecom equipment 102 receives carrier wave aggregation configuration, and the carrier wave aggregation configuration includes At least one licensed radio frequency frequency range component carrier (such as licensed radio frequency frequency range component carrier 106) and at least one exempt from licensed radio frequency Frequency range component carrier (such as exempting from licensed radio frequency frequency range component carrier 108).
